Abstract: A method of producing a porous material having open pores comprises stirring a mixture comprising (i) an epoxy compound having at least one epoxy ring in a molecule, (ii) a hardener capable of reacting with the epoxy compount to harden the epoxy compound, (iii) a filler and (iv) water to form an emulsion slurry having a low viscosity and containing the soluble salts uniformly dispersed therein, casting the resulting emulsion slurry in a water impermeable mold and then hardening the slurry while maintaining the water content thereof, and wherein the soluble salts are added to the mixture. The method makes it possible to produce a large scale porous material having open pores and a complicated shape whose shrinkage factor during hardening and water and air permeabilities are controlled to desired levels respectively while scattering thereof is reduced.

Abstract: To determine the asymmetry of the line spread function in digital imaging systems, two modulation-transfer functions are calculated by differentiation of the edge spread function followed by Fourier transformation. To that end a method is used in which a radiation intensity distribution spatially modulated by a test object (5) is displayed on an input screen (7) of a detector (9) which is connected to a digital data processing device (13) for storing detector signal values in memory locations which correspond to picture elements of the input screen, the radiation intensity distribution is spatially and block-wise modulated, whilst in the data processing device first the derived value of the detector signal values is determined for picture elements located along a picture line which extends transversely of a modulation direction, whereafter from positive and negative derived values, respectively, there is calculated by Fourier transformation a sequence of frequency-consecutive local maxima, from whose envelope the modulation-transfer function is determined.

Abstract: A stainless steel mandrel (10) is etched with a negative pattern (16) of an electrical circuit that is to be made with the mandrel and then covered with Teflon (20) which is subsequently lapped to provide a coplanar surface of stainless steel and Teflon. A pattern of electrical conductors (30) is then electroformed, as by electrolytic or electroplating, on the exposed surfaces (24) of the mandrel between the embedded Teflon (16). Surfaces of the electrical conductors (30) of the circuit are then processed, as required for enhanced adhesion to a substrate, and a dielectric substrate (34) of polyamide and acrylic is then laminated upon the surface of the mandrel over the electroformed conductors (30) so that the dielectric substrate (34) adheres to the conductors (30). The assembly of dielectric substrate (34) and conductors (30) is then separated from the planar surface of the mandrel (10) and its embedded Teflon (16).

Abstract: Lead frames for microchips and other integrated circuit dies are produced by a continuous manufacturing method and apparatus in which silver spot plating is done prior to etching away unwanted portions of the lead frame substrate. A flexible substrate of a metal alloy is fed continuously from a reel, then spot plated with silver, coated with a photosensitive material, and exposed to intensive light in an exposure chamber using a photoresist or masking tool of predetermined design. The exposed photosensitive material is developed chemically, etched in acid, and placed in a chemical solution to remove any remaining unwanted material. The strip is then dried, cut to predetermined lengths and boxed for shipment. If necessary, the strip is downset and taped before packaging. In a presently preferred process, the metal alloy substrate is 42 alloy (Fe + Ni), and the selective spot plating is silver 100 to 150 microinches (2.5 to 3.8 mucrons) thick. The silver does not dissolve in the etchants and therefore has to be removed from exposed areas, preferably by "reverse" plating techniques.

Title: Enhanced capillary zone electrophoresis and apparatus for performance thereof.
Inventor: BLANCHARD WILLIAM C
IPC: G01N27/447
Filed: 1991-02-07
Abstract: Capillary zone electrophoresis is enhanced by the application of an electric field across the interior of the capillary tube. This external electric field is applied through a conductive member at the exterior of the capillary tube. The external field vectorially couples with the internal field, controlling the polarity and the magnitude of the surface (zeta) potential on the interior surface of the capillary. The control of the surface (zeta) potential reduces adsorption of macromolecular onto the interior surface of the capillary tube, by inducing electrostatic repulsions between the macromolecules, and the capillary surface. Additionally, the control of the surface (zeta) potential can retard, and even reverse, electroosmotic flow, depending upon the magnitude of those fields.
